Abstract:
A bicycle control device is configured with an operating member that selectively controls a braking unit and a shifting such that shifting and braking can be easily performed while braking. The operating member has a user engagement part and a wire connecting portion with a support structure pivotally coupled to the user engagement part and a wire attachment member movably coupled to the support structure by a universal coupling. Also the operating member can perform a braking operation without movement of the main parts of the shifting unit. The shifting unit is movably disposed around a center shifting axis to provide a compact structure. The shifting unit has a position control mechanism that is configured to operate a positioning member that moves through two of a plurality of predetermined shift positions during a single progressive movement of the operating member.
